"A wild new theory has claimed the origins of life on Earth were delivered by aliens who were terraforming the planet into a habitable world billions of years ago. Robert Endres, a scientist from Imperial College London, said that the building blocks of life on Earth might be too complex to have formed naturally, meaning they would have needed something (or someone) to help kickstart the process."
"Endres theorized that this would have happened around 4.2 billion years ago, shortly after Earth cooled and water formed, with extraterrestrials potentially using a spacecraft or probes to deliver microbial 'starter kits' to the young planet. The scientist added that the natural formation of life without any help was unlikely because the amount of chemical 'order' needed to form the first simple cells would have been too much to come together in just 500 million years."
Directed panspermia proposes that advanced extraterrestrials intentionally sent microbes or simple life forms to Earth roughly 4.2 billion years ago after the planet cooled and water formed. The hypothesis argues that chemical order required to assemble the first simple cells was too great to arise naturally within about 500 million years, making external seeding more plausible. Proposed delivery methods include spacecraft or probes carrying microbial 'starter kits.' The idea traces back to Francis Crick and Leslie Orgel in the 1970s and challenges chance-based chemical origin models. A 2024 US Pentagon report found no evidence of alien life.
